GOP Candidates Hoping to Avoid Runoff

"That is my intention, is to do it without a runoff," Perry said, adding that "it's not the end of the world" if that does not happen.

"We will at the end of the day lay out a good, solid reason for people to vote for us," Perry said after speaking to about 400 people at a Fort Worth Chamber of Commerce luncheon. "It's pretty simple for most people: Do you want to go with the Washington crowd and their mentality of `spend it all, spend it now' or do you want to stick with fiscal, conservative leadership that they've seen for the last six, eight years?"

According to the poll, Perry leads with 45 percent support among likely Republican voters, with Hutchison at 29 percent.

Republican activist Debra Medina, whose campaign has attracted insurgent Tea Party voters, was at 17 percent, and 8 percent of voters were undecided.

If no candidate wins a majority, a runoff between the top two finishers would be April 13.

In Houston on Friday, Hutchison called on supporters to use Twitter, Facebook, e-mail and even old-fashioned snail mail to get the word out about the urgency to vote in the primary.

Speaking to a select group of largely female supporters, Hutchison -- with former first lady Barbara Bush at her side calling for people to vote against Perry -- said it was time for Perry to step aside and called for a two-term limit for the gubernatorial post. Perry is running for a third term in office.

"Eight years is enough," Hutchison said, but dodged a question by The Associated Press about the poll numbers.

"The polls that count are getting ready to happen so I don't think it makes sense to focus on the ones that don't," she said.
